The front wheel is made as driving motorised wheel, to side surfaces of frame two wheelchair base-changing mechanisms are attached each one of which consists of attached to frame body into vertical hole of which fork is installed with possibility to turn around its vertical axis by 180° and with fork fixation in two end positions using fixation mechanism, into this fork horizontal axle is installed on which rear wheel is mounted with possibility of its rotation around this horizontal axle. Central plane of rear wheel is shifted relative to vertical axis of fork rotation for amount of eccentricity, and wheelchair is provided with electric drive and its control.EFFECT: cutting time and simplification of wheelchair base changing.5 cl, 6 dwg |
